Government proposed a more flexible and market-oriented framework under Draft Corporate Average Fuel Efficiency (CAFE)-3 norms, aimed at reducing vehicular emissions while easing compliance for automakers. The new framework shifts focus from the earlier small-car vs large-vehicle debate to overall fleet emissions reduction, encouraging Original Equipment Manufacturers (OEMs) to adopt cleaner technologies such as electric vehicles, hybrids, and biofuels.
It introduces mechanisms like carbon credit trading and relaxed penalties, aligning industry growth with India’s long-term climate goal of achieving net-zero emissions by 2070. The CAFE-3 phase will be implemented from April 2027, covering period FY 2027–28 to FY 2031–32.
About Corporate Average Fuel Efficiency (CAFE) Norms
CAFE norms are regulatory standards that require automobile manufacturers to meet fuel efficiency and emission targets across their entire vehicle fleet, rather than for individual vehicles.
Objectives
- Reduce fuel consumption in the transport sector
- Lower greenhouse gas emissions (CO₂)
- Decrease dependence on crude oil imports
- Promote clean and energy-efficient mobility technologies
Key Features
- Applicable to fleet-wide average emissions (gCO₂/km)
- Implemented in phases:
- CAFE-1 (2017)
- CAFE-2 (from 2022)
- CAFE-3 (proposed from 2027)
- Compliance measured using Modified Indian Driving Cycle (MIDC)
- Integral to India’s climate commitments and sustainability goals
Need for Strengthening CAFE Norms
- Transport sector is a major contributor to emissions
- Rising vehicle ownership increases fuel demand
- Heavy reliance on oil imports exposes economic vulnerability
- Global climate commitments require systematic emission reduction
- Need to balance environmental sustainability with industrial feasibility
Key Highlights of Draft CAFE-3 Norms
Flexible Compliance Framework
- Moves away from strict penalty-based enforcement
- Focus on ease of compliance and industry adaptation
- Encourages participation rather than penalising deviations
Carbon Credit Trading System
- Automakers exceeding targets can generate carbon credits
- Credits can be sold to manufacturers failing to meet targets
- Creates a cap-and-trade-like mechanism within the auto sector
- Helps reduce compliance costs and improve efficiency
Offset Mechanism via Bureau of Energy Efficiency
- Manufacturers can offset emission deficits by purchasing credits
- Credits available through the Bureau of Energy Efficiency
- Ensures compliance flexibility for lagging firms
Progressive Emission Reduction Targets
- Emission limits to decline from 113 gCO₂/km (FY27) to 78.9 gCO₂/km (FY32)
- Ensures gradual but firm tightening of standards
Promotion of Clean Technologies
- Higher weightage assigned to:
- Electric Vehicles (EVs)
- Hybrids and Plug-in Hybrids
- Flex-fuel vehicles
- Helps reduce weighted average emissions of OEM fleets
Support for Alternative Fuels
- Encourages biofuels and ethanol blending
- Promotes flex-fuel vehicles
- Enhances energy security and diversification
Reduced Penalty Orientation
- Relaxation of strict penalties
- Shift towards incentive-driven regulatory approach
- Promotes collaboration between government and industry
Implementation Timeline
- Applicable from FY 2027–28 to FY 2031–32
- Provides sufficient transition time for the automobile sector
Additional Technical Provision
- Clean vehicles receive higher weightage in emission calculations
- Lower CO₂ vehicles reduce the overall fleet emission average
- OEMs can offset debit balances through credit purchases from BEE
Significance of Draft CAFE-3 Norms
- Encourages innovation in green mobility technologies
- Supports India’s net-zero target (2070)
- Introduces market-based environmental regulation
- Reduces compliance burden through flexibility mechanisms
- Aligns industrial growth with sustainability goals
